Flood resilience loci and interact in seedlings established underwater.

Crops with resilience to multiple climatic stresses are essential for increased yield stability. Here, we evaluate the interaction between two loci associated with flooding survival in rice ( L.).

QTL mapping for tolerance to anaerobic germination in rice from IR64 and the landrace Kharsu 80A.

Direct seeding of rice often results in poor crop establishment due to unlevelled fields, unpredicted heavy rains after sowing, and weed and pest invasion. Thus, it is important to develop varieties able to tolerate flooding during germination, also known as anaerobic germination (AG), to address these constraints. A study was conducted to identify QTLs associated with AG tolerance from an IR64/Kharsu 80A F mapping population using 190 lines phenotyped for seedling survival under the stress.
